Semantic Hearing: Programming Acoustic Scenes with Binaural Hearables
Bandhav Veluri, Malek Itani, Justin Chan +2
Imagine being able to listen to the birds chirping in a park without hearing the chatter from other hikers, or being able to block out traffic noise on a busy street while still be…
Underwater 3D positioning on smart devices
Tuochao Chen, Justin Chan, Shyamnath Gollakota
The emergence of water-proof mobile and wearable devices (e.g., Garmin Descent and Apple Watch Ultra) designed for underwater activities like professional scuba diving, opens up op…
Wireless earbuds for low-cost hearing screening
Justin Chan, Antonio Glenn, Malek Itani +5
We present the first wireless earbud hardware that can perform hearing screening by detecting otoacoustic emissions. The conventional wisdom has been that detecting otoacoustic emi…
Real-Time Target Sound Extraction
Bandhav Veluri, Justin Chan, Malek Itani +3
We present the first neural network model to achieve real-time and streaming target sound extraction. To accomplish this, we propose Waveformer, an encoder-decoder architecture wit…
Underwater Acoustic Ranging Between Smartphones
Tuochao Chen, Justin Chan, Shyamnath Gollakota
We present a novel underwater system that can perform acoustic ranging between commodity smartphones. To achieve this, we design a real-time underwater ranging protocol that comput…
Underwater Messaging Using Mobile Devices
Tuochao Chen, Justin Chan, Shyamnath Gollakota
Since its inception, underwater digital acoustic communication has required custom hardware that neither has the economies of scale nor is pervasive. We present the first acoustic…
Testing a Drop of Liquid Using Smartphone LiDAR
Justin Chan, Ananditha Raghunath, Kelly E. Michaelsen +1
We present the first system to determine fluid properties using the LiDAR sensors present on modern smartphones. Traditional methods of measuring properties like viscosity require…
Identifying Pediatric Vascular Anomalies With Deep Learning
Justin Chan, Sharat Raju, Randall Bly +2
Vascular anomalies, more colloquially known as birthmarks, affect up to 1 in 10 infants. Though many of these lesions self-resolve, some types can result in medical complications o…
DeepSense: Enabling Carrier Sense in Low-Power Wide Area Networks Using Deep Learning
Justin Chan, Anran Wang, Arvind Krishnamurthy +1
The last few years have seen the proliferation of low-power wide area networks like LoRa, Sigfox and 802.11ah, each of which use a different and sometimes proprietary coding and mo…
Contactless Cardiac Arrest Detection Using Smart Devices
Justin Chan, Thomas Rea, Shyamnath Gollakota +1
Out-of-hospital cardiac arrest (OHCA) is a leading cause of death worldwide. Rapid diagnosis and initiation of cardiopulmonary resuscitation (CPR) is the cornerstone of therapy for…
Surface MIMO: Using Conductive Surfaces For MIMO Between Small Devices
Justin Chan, Anran Wang, Vikram Iyer +1
As connected devices continue to decrease in size, we explore the idea of leveraging everyday surfaces such as tabletops and walls to augment the wireless capabilities of devices.…
